如何搭建spring mvc框架

spring框架jar包
1、下载spring源包
spring地址：http://www.springsource.org/download
我下的是spring-framework-3.1.0.RELEASE-with-docs.zip
下载依赖包：spring-framework-3.0.5.RELEASE-dependencies.zip
注意官网上3.0.3版本以后同版本依赖包不提供下载
2、导入所需jar包
引入dist目录下除了下面三个其余所有包
org.springframework.web.struts-3.1.0.RELEASE.jar
org.springframework.spring-library-3.1.0.RELEASE.libd
org.springframework.web.portlet-3.1.0.RELEASE.jar
引入依赖包下com.springsource.org.apache.commons.logging-1.1.1.jar及com.springsource.org.aopalliance-1.0.0.jar
spring框架配置
1、web.xml配置

[html] view plain copy

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID"
version="3.0">

contextConfigLocation

/WEB-INF/spring-servlet.xml


org.springframework.web.context.ContextLoaderListener



spring
org.springframework.web.servlet.DispatcherServlet
1



spring
/


2、应用上下文配置
spring-servlet.xml即配置用于开启基于注解的springMVC功能，照web.xml中设定，路径为WEB-INF下
[html] view plain copy
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">







Demo例子
1、根据spring-servlet.xml配置的包路径（com.mvc.rest）新建Constroller
[java] view plain copy
package com.mvc.rest;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class RestConstroller {
public RestConstroller() {}
@RequestMapping(value = "/login/{user}", method = RequestMethod.GET)
public ModelAndView myMethod(HttpServletRequest request,HttpServletResponse response,
@PathVariable("user") String user, ModelMap modelMap) throws Exception {
modelMap.put("loginUser", user);
return new ModelAndView("/login/hello", modelMap);
}
@RequestMapping(value = "/welcome", method = RequestMethod.GET)
public String registPost() {
return "/welcome";
}
}
2、建jsp视图
视图路径在spring-servlet.xml配置（/WEB-INF/view/），据上述RestConstroller 类，我们在WEB-INF下建立view目录，在view下建立welcome.jsp及login/hello.jsp
welcome.jsp随意，hello.jsp代码如下：
[html] view plain copy
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>









你好:<%=request.getAttribute("loginUser") %>，现在时间是<%= new Date() %>


3、部署访问
